UNITED STATES CONRAD MORCHEN AND PETER DOERFER, OF EATON, WISCONSIN.

IMPROVEMENT IN STUMP-EXTRACTORS.

Specification forming part of Letters Patent No. 135,658, dated Fetruary11, 1873.

To all whom it may concern:

Be it known that we, CONRAD MoEonEN and PETER DOERFER, of the town ofEaton, county of Manitowoc, in the State of Wisconsin, have inventedcertain Improvements in Stump-Extractors, of which the following is aspecification:

N attire and Object of the Invention.

Our invention relates to a stump-extractor constructed in such a mannerthat the leverage is so short that almost any stump can be extractedwith it by the aid of two men, and the lever has another lever at eachend of it attached by pins in such a way that they can be regulated soas to raise or lower the ends of the operating-lever, and thus increasethe power of the machine, and also make it handier to work-With.

Description of the Drawing Forming Part of this Specification.

Figure 1 is a perspective view, and Fig. 2 a sectional view.

A is the frame; B, a hook, which keeps the frame from spreading; C, theoperating-lever; D, an iron cap, which holds the top of the frametogether. One side of this iron cap is secured permanently to one sideof the frame, and the other side is secured by a pin or pins in an eyeor eyes, so that the frame can swing nearer together orfurther apart,and thus accommodate itself to the nature of the ground. D, bars orstandards with holes in them for the insertion of iron pins to form afulcrum. These bars or standards are fastened at their lower ends tolever C by pins, and pass up through holes in cap D. E E, pins, whichare thrust into the holes in D F, a hook or fastenin g attached to thebottom of lever C, and into the lower end of which hang hooks G, whichare used to hook under a stump. H, levers attached to the ends of leverC; I, brackets on the ends of lever C; K, pins, which are passed throughthe brackets and hold levers H The operation of this machine is asfollows: Set the frame over a stump; lower the lever C down so as topermit the securing hooks Gr under the stump; hook B is hooked-into theeye so as to prevent the frame from spreading; then take hold of theends of lever C and tilt one end down, and, as the standard near theother end rises, put in one of the pins E; then tilt theother end down,and as the other standard rises shift the pin E down into the holebelow, and so on alternately till the stump is raised out of the ground.If more poweris wanted, or if the end of the lever C is too high or toolow for working handy, then put in levers H, and arrange it so as towork as described. a

Claim.

We claim as our invention the followingcoiu bination, the other partsbeing old:

The frame A with the curved iron-plate at tachment D, in combinationwith the standards D, levers C H, link F, and hooks G, all constructed,arranged, and operated as described.
